1. First save the file in dxf format, then reopen CAD, open the file in dxf format just saved, and save it in dwg format, so as to remove the production mark of Autodesk Education Edition when printing.

2. Use other dwg version conversion tools (such as AcmeCADConverter) to convert to R 14.

3. Save it as a DWT template file and save it back to DWG after opening.
